Is mild cerebral edema a cause for concern post stent placement?

Answered by

Question: Hello again, Dr. Taka. I thought you'd be interested to know that the stent inserted into my stepfather's carotid artery was successful and he will return home tomorrow. The doctor said he had some slight swelling in the brain which might contribute to the periodic confusion. He kept thinking he was in a hotel instead of the hospital, and kept asking why he was there. I spoke to him today but he was totally fine. He just complained that the food in the hospital was tasteless! Anyway, the doctor hopes the confusion will improve once he's back home.

Detailed Answer:Hello again!

Thank you for letting me know the outcome, I am glad that the procedure went well.

If the stroke he's had is a small one as they say then there shouldn't be much swelling. Anyway whether due to the low perfusion from the narrowed artery, to the swelling, to the loss of cells from the stroke, to the dementia exacerbated from the stay in the hospital or (what is more likely) from all of these contributing together, improvement is expected once he's back.

My mom had gullbladder lipascopic surgery 3 days or so ago and is now experiencing a throbbing pain in her carotid artery in her neck, should we take her to the emergency room? I also thought to check her bloodpressure after reading some articles. Was wondering if this throbbing was do to anestesia, or the surgery its self?

I just had a Bilateral carotid artery ulstrasound with the following findings. The right common carotid artery peak systolic velocity is 87 cm/second and the internal cartotid artery peak systolic velocity is 216 cm/second. Pre sclerotic right ICA ststolic velocity measures 86, with post dynamic velociity measuring 205 centimeters per second. The systolic velocity ratio is 2.5. On the left, the common is 66 cm/second & internal is 424 cm/second. Pre stenotic velocity is 129 and post is 179 cm/sec. The systolic velocity ratio is 3.1. I am seeing a surgeon tomorrow. Are these numbers alarming?

Thrombotic plaque is seen in the origin of Left Internal Carotid artery leading to 50-60% blockage.3. Calcified plaque also seen in right common carotid bulb with no flow limiting disease.4. Atheromstous plaque is seen right common Carotid artery and external carotid artery with no flow limiting disease.5. Diffuse atheromatous wall changes seen in bi-lateral carotid vessels.SUGGESTED NECK ANGIOGRAPHY FOR FURTHER EVALUATION.

My mom (74 yrs) 5'3" 110 lbs - did a lifeline screening test for AFIB and something came up strange - heart rate was 053 beats/min - what does this mean? Is the blood going thru very slowly? Also the carotid artery test came up as mild. What can she do to fix this problem? Do not recommend drugs or surgery here, they are NOT an option. Pls advise.
